e08ad14696 Fix error path in vg_make_handle(). 
Enter the error condition if either of the allocations fail, and
don't use dm_pool_zalloc if dm_pool_create fails.

405366fd48 Properly release VG memory pool in metadata manipulation code. 2009-04-10 10:01:08 +00:00

8e1d5615b4 Introduce memory pool per volume group. 
Since now, all code reading volume group is responsible for releasing
the memory allocated by calling vg_release(vg).
(For simplicity of use, vg_releae can be called for vg == NULL,
the same logic like free(NULL)).

Also providing simple macro for unlocking & releasing in one step,
tools usualy uses this approach.

The global memory pool (cmd->mem) should be used only for global
physical volume operations.

This patch have to be applied with all subsequent patches to complete
memory pool per vg logic.

Using separate memory pool has quite bit memory saving impact when
using large VGs, this is mainly needed when we have to use
preallocated and locked memory (and should not overflow from that
memory space).

6fe905c705 Properly copy the whole pv structure for later use. 
The all_pvs list, used in vg_read, should make its own private
copy of pv structures, otherwise (when vg will use its own pool)
it will point to released memory pool.
The same applies for get_pvs() call.

Patch adds pv_list copy helper and adds explicit memory pool
parameter into _copy_pv.

(Please note that all these helper functions cannot guarantee that
vg related fields are valid - proper vg read & lock must be used
if it is requested.)

ec5703ea07 Allocate new pv->vg_name from pool, it can be destroyed later.

7f436a0f39 Fix lv_count when manipulating with snapshots and max_lv is set. 
Patch fixes these problems:
 - during the snapshot creation process, it needs create 2 LVs,
   one is cow, second becomes snapshot.
   If the code fails in vg_add_snapshot, code lvcreate will not remove
   LV cow volume.

 - if max_lv is set and VG contains snapshot, it can happen that
   during the activation lv_count is temporarily increased over the limit
   and VG metadata are not properly processed
   see https://bugzilla.redhat.com/show_bug.cgi?id=490298

 - vgcfgrestore alows restore with max_lv set to lower valuer that actual
   LV count. This later leads to situation that max_lv is completely ignored.

 - vgck doesn't call vg_validate(). It should at least try:-)

0241c10fd6 Fix validation of dataalignment value introduced in previous commit. 2009-02-23 16:53:42 +00:00
Alasdair Kergon
8929ce6651 Add --dataalignment to pvcreate to specify alignment of data area. (mbroz) 
This patch is not fully tested and leaves some related bugs unfixed.

Intended behaviour of the code now:

  pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.

  In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.

  Currently, the field storing the size of the data area in the PV label
header always holds 0.  As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).

4631e58782 Rename get_vgs() to get_vgnames() and clarify related error messages. 
get_vgs() really returns a list of vgnames.  In the future we will use
get_vgs() to return a list of vg structures, similar to get_pvs().

25b733809a Merge with text format branch. 
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

15c325f06a o Use new LCK_HOLD flag to indicate whether lock should be held on return 
from lock_vol() - otherwise it now attempts to acquire the lock and then
  immediately releases it.
o Extend the id field in struct logical_volume to hold VG uuid + LV uuid
  for format1. This unique lvid can be used directly when calling lock_vol().
o Add the VG uuid to vgcache to make VG uuid lookups possible.  (Another
  step towards using them instead of VG names internally.)

and add severe warning if it's used to make a device seem bigger than
  it really is.  This is not an option people should be using as it
  breaks metadata integrity.
o Use uint64_t throughout (rather than unsigned long long)
o Convert a few messages that contain pathnames into the more common form:
  pathname: message
